This invention relates to portable electric I lamps and particularly to that type which can be carried about on the person and which is readily attachable to a small artlcle, such as abook cover forconcentrati1ig thelight v from the lamp at any desired point; 7

My invention contemplates the provision of a reading lamp which may be easily carried about the person, a substantialthough light frame for supporting the lamp and en" closing the wires thereto, a suitable base by which the lamps-may be attached at any desired. projecting surface, such'as, the cover .ofa' book, and terminals which may be readily connected electrically and physically, to the u'sual flat' prong terminals. of a pocket battery. i v

. r The various objects" of myinvention will be clear from thedescription which follows,

and from the drawings, in which- Fig. 1 is a front elevation of the preferred 'fOIIIl of my invention. 1

Fig. 2 is a side elevation of the same.

Fig 3 is a perspectiveview of one of the terminal connections by meansof which cur rent is conducted to the lamp,'and

Fig. 4.is a' similar viewof the other terminal.

In the illustrated embodiment of invention I provide a base 6, preferably rectangular in cross-section, of suflicient length to be readily attachable toa spring clip of any of the conventional types in a manner described Q more fully hereinafter. Preferably U-shaped clamps'as' a, having a lower leg a and an upper leg a are secured preferably over the ends of said base by means i of the thumb screws 0 passing through the upper leg a and the base 7), the under surface of the leg a bemg arranged to engage the upper surface of the base 6. The upper surface of the leg a of the clamp member a is adapted to engage one of the surfaces, of the clip aforementioned, and the under surface of the-base b is adapted to engage the opposite surface of said clip, whereby said 7 clip is removably secured in place between the undersurfaces of said base Z) and the upper surface of said leg a.

A rigid frame preferably of brass tubing is provided for supporting a suitable lamp,

said frame being preferably made substan-V' tially.L-shaped in fornr for easy carrying about in the pocket of the user, and comprising two substantially parallel members-d and h, the member (Z being preferably of greater length than the member :A frame member f preferably of thesame ma- 'terial as that ofthe members 0! and h is'op eratively connected to said members, by

means of the right angle elbows e and jgre'- spectively. One end of the frame member ,h

is sccuredto the elbow g whilethe other end is suitably fastened into the: swivel connection z of'the usual type for allowing adjustment of the'lamp at'anyangle Within the limits of said connection.)

The 'lamplc is secured in a of the conventional types, which socket is. in turn, connected to, theflower m ember -of socket of any i i the swivel connection 2'. 'jGurrent is supplied to'said socket and therethrough to the lamp by means of suitable'wiresnot shown, entering the frame member 'cl through a suitable opening as a through the lower end thereof, entirely enclosed by and. concealed in said tubing, and passing through-said'tubing to].

the usual connections in the socket 7'. One

of said wires terminates in the battery connection 0 which is preferably made of sheet material, and which has an openingv 39 near one end thereof in which the conducting wire may be readily secured. Said terminal 0 has a portion 0' bent back on itself and spaced from" the remainder of the terminal .a suflicient'distance to allow the flat sheet metal terminal prong of the usual small pocket battery to be inserted therebetween in intimate contact with the battery 'ter-f minal. The-other conductingwire is connected to the terminal gpreferably U-shapedj and having an opening r near the closed portion thereof, through which the end'of the'conducting wire is passed. The second. battery terminal prong isfp'assed between the branches of the U and makes quick, slid able, but intimate contact with said branches. It will be understoodthat there is suflicient spri'ng action in the'terminals o and Q to cause said terminals to engage the battery term nal prongs wlthout danger of becoming loose or slipping'off therefrom. Theoperatlon in my improved .device 18 as followszThe thumb screws 0 are loosened sufliciently'to allow the'insert'ion over the legs a thereofof a spring clip afterwhich said screws are tightened to secure saidclip inplace. The entiredevice is then ready to be attached to a flat objectas, for instance, the cover of a book in proper' position'and the lamp may beadjusted to. cast its light directly onthe page to be read, When the found to be needed.

use of the device is to be discontinued one or both ofthe terminals 0 and g may be slipped off the battery terminal and the entire device carried in the pocket until it is It will be seen that my'improved device is of rigid substantial construction while allowing adjustment thereof to the proper position to cast light on the desired point. It will further be seenthat my device 18 's'mall enough andof suitable shape to be appended claim.

I-c'laimz g r o V In a locket eleotric boo'k lamp, a rigid tubular -shaped frame comprisinga pair of, hollow members arranged in parallel relation, one of said members being longer than the other, the longer of said members having an opening spaced a-bov'e'the lower end thereof, a third hollow ,it'rame member substantially perpendicular to said parallel members, an elbow at each end ofsaid third member joining said third member to said parallel members, and adapted, to receive wires passing through said opening and through said hollow members to the extremity of the shorter of said parallel members, a swivel joint at the extremity of the shorter ofsaid parallel members, a lamp socket at the end" ofsa-id joint to which said wires are connected; means at the eX- tremity of the longer of said parallel frame members for removablysecuring saidframe to another article comprising an'elc-ngatech substantially rectangular-base rigidly 'se cured at the center thereof and at right angles to said longer frame member a removable U shaped clamp'coveringf each end of said base, said clampcomprismga pair of substantlallly parallel legs and a Web joining the outer ends of said legs, vsaid.

legs being spaced apart to allow the of a thin object between the under face of said base and upper. faces of the lower le s,

and screw passing through each 0ft e upper legs of the clamps and through said base whereby a spring clip or a book cover may be inserted betweensaid base a-n'dithe lower legs of 'the'clamps and secured in place by the movement of said screw.
